What is *Tashkeel* (diacritics), and why is it the most important feature in any Arabic voiceover—especially when using artificial intelligence?
In Arabic, diacritics are not merely a linguistic embellishment; rather, they constitute a precise system for governing pronunciation and meaning . While many Arabic speakers can easily read texts without diacritics, the situation changes radically when converting those texts into audio using human voice-over artists or artificial intelligence .
What is vocalization?
Tashkil is the use of diacritics (fatha, damma, kasra, sukun, tanwin, shadda, etc.) to precisely determine the pronunciation of letters and words. For example:
- "To kill" ≠ "To be killed"
- "sajjala" ≠ "sijill"
Vowel marking eliminates ambiguity and clarifies meaning, especially for words with multiple meanings and forms.
Diacritics and Their Importance in Voice-Over
1. Ensuring correct understanding
The voice performer (whether human or synthetic) needs to know the precise pronunciation of every word. Diacritics guide the performance and prevent errors.
2. Improving the final audio quality
Vowel-marked text enables artificial intelligence to produce natural, clear speech, free from stumbling, stuttering, or mispronunciation.
3. Saving time and effort
In the absence of diacritics, the automated system is forced to guess—or the text must be entered multiple times to test the pronunciation—whereas text with diacritics reduces corrections and speeds up the process.
Visual Art and Artificial Intelligence: A Crucial Relationship
With the development of AI-powered text-to-speech (TTS) systems —such as "Neural TTS" models—these systems have become capable of simulating the human voice with remarkable accuracy. However, they face a fundamental challenge regarding the Arabic language:
The absence of diacritics renders pronunciation mechanical and difficult to understand, or completely incorrect.
This is where the importance of vocalization becomes apparent:
✅ Without diacritics:
The man took the pen.
It might be pronounced "akhadha ar-rajulu al-qalama" or "ukhidha ar-rajulu al-qalamu"—two possibilities with completely different meanings.
✅ With diacritics:
The man took the pen.
Artificial intelligence pronounces it correctly 100% of the time, without human intervention.
How does the "Makna" platform contribute to this challenge?
The Moknah platform ( Moknah.io) offers an Arabic diacritics service specifically designed for voiceover ; it goes beyond merely adding diacritics to also include:
- Adapting the vocalization according to the phonetic context (and not merely the grammatical one).
- Improving synthetic speech to achieve a natural and pleasing delivery.
- Integrating diacritics directly into the audio production workflow , without the need to send the text to external tools.
This makes Makina one of the rare platforms that combines professional sound shaping with AI-powered audio processing into a single, integrated experience , saving producers time and significantly enhancing the quality of the final result.
Summary
In the Arabic language, diacritics are not merely a linguistic tool but an essential technique for comprehending texts and accurately converting them into speech . With the rise of artificial intelligence in speech synthesis, diacritics have become the bridge connecting Arabic text to its correct and intelligible pronunciation .
